        Solutions 
                      Solution Description 
        This solution is used within the U.S.  It combines standards associated with US: SAE Signal Control Messages with those for I-I: Internet (US). The US: SAE Signal Control Messages standards include upper-layer standards required to implement signal control information flows.  The I-I: Internet (US) standards include lower-layer standards that support secure communications between ITS equipment using X.509 or IEEE 1609.2 security certificates.
